wARr-HANDLING MACHINE.

loom harnesses, it is essential that Ithe threads vbe. selected in proper sequence,r in orderthat the different colored threads shall Y be` drawn Vthrough the proper. eyes ofthe isa view taken in the harnesses.` Similarly, whenl uniting` 4a striped warp to a section of old warp, .itis essential that the 'threads of thenew warp b e tied to the corresponding threads of-the old warp. As thereisa possibility that threads maybe crossed or improperly-leased or missing'in one-or both of the warps, it is important that the operation of the thread selectors be carefully watched,and that any necessary corrections be made before the selected thread or threads are placed Iin the knotter. l

The object of this invention is to provide means to assist the operator of a warp drawing machine, warp tying machine,` lease-V picking machineor other warp-handling machine, to discover` errors inathe selection or arrangement. ofthe-threads, so that the necessary correction maybeinade. l

Y 10,1915, by Thomas E. Bingham and Earle D, Parker and in British Patent No. 5,57 4, of 1915. As reference may be had to the patent'to be issued upon that application l and to said British patent for a full understanding of the construction and operation of theV warp-tying machine, I have herein illustrated onlyso much of said machine as coacts directly with the present invention.

The two warps to be united are supported horizontally, oneabove the other, in suitable clamps, one of the clamps for thenew warp `being shown at 77 in Fig. 2.

`The particular devices herein illustrated for selecting Vindividual threads from vthe t warps are'designed to Select threads from an` end-and-end lease, the threads of each warp being leasedover two rods 128. Fig. 1 shows one of-the lease rods for each warp. Fig. 2 illustratesthe two lease rods for the -lower Vor new warp.` The rods 128 lare supported at one end by suitable vmeans not herein shown, but fully4 disclosed vin said Bingham & Parker application. AThe other ends ofthe `lease rods 128 are supported uponv the carriageV 136 on which is mounted the selecting and uniting mechanisms. The carriage is arranged tot-ravel upon a guide 137 'on the bed of the machine.

YPower is transmitted to the mechanisms on the carriage 136 .by means of a shaft 138 (Fig. 1)' which is supported by the bed of the machine. 4Said shaft .may be driven in any suitable manner. l l Upon .thecarriage 136 is la bearing 143 in which is rotatably mounted a sleeve 144, said sleeve being slidably mounted upon the shaft 138. Fixed to the sleeve at opposite sides of the bearing 143 are a pinion 145 and a bevel gear 146. The pinion 145 actuates theV thread-selecting mechanism, while the bevel gear 146 actuates theV remaining mechanisms mountedon `the carriage 136. -Powergistransmitted from the shaft 138 tothe sleeve 144 by means comprising a clutch member 147 splined to the shaft and slidable therealong, the member 147 being caused to travel with the carriage 136 by a bracket 148].`1Xed to the carriage and engaging in fa groove 149 in the clutch member. On.` the sleeve 144 issplined a clutch collar 150 which is provided in one end with clutch member147. A. hand lever 153 piv- For each warp, there are provided two` selectors 151 operating at opposite sides of the point where the threads cross each other between the lease rods-128. Each selector is fixed to a tubular stem 155 ,which is mounted for rocking movement ina. support 156 on the carriage 136. The selectors for the new warp. operate simultaneously with those-for the old 'wa-rp, onethreadfrom the new warp and one thread from the old warp 4being simultaneously selected for presentation to the uniting mechanism.

1As shown in Fig. 1, the selectors forthe newA warp are located rearwardly of the old warp selectors, in order to avoidinterference betweenthe selectors as they oscillate, and so l that the selected oldfwarp thread `shall be spaced away; from the selec-ted vnew-warp threadV when the latter is in operative relation to the color-indicating means p hereina-fter described.

- Y In the present embodiment, the kuniting mechanism consists of a knotter. Any suitable form of; knotter may be employed. That herein shown comprises a rotatory tying bill 25 similar to the one fully described Y in Patent No. 959,592, datedfMayv 31, 1910, said bill being provided with shearing edges whereby the threads are sheared .afterthe loops of Athe knothave been formed. rI`he tying bill is continuously rotated by means fully described in the Bingham t Parker application. c The threads selected from the warps by the selectors 151 are moved tothe knotter by four'carry-in fingers only three Aof which are shown in the present drawings. l The finger 191 and a corresponding finger (not shown) act upon the upper warp thread, and the fingers 192 and 193 operate on the lower warp thread. The lingers 191 and l193 are located at-one side of the knotter, while the finger 19.2 and the fin'gerwhich is not shown herein are at the opposite side. Said finge-rs have forked ends adapted to engage the threads. The means for actuating the carry-in fingers is fullyV disclosed in the'Bingham & Parker application and therefore need not be herein described.- It may be stated, however, `that said actuating means includes relatively stationary plates 202V (one for each carry-in linger), each plate having a'cam groove 198 therein. v

The waste ends, namely the thread portions sheared off by the tying 'bill 25, are drawn out of the wayv by a hook 218. The shank of said hook isslidably and pivotally supported upon a relatively stationary stud 219 which extends th'rough an elongated opening 221 in said shank. The hook 218 is pivoted to a crank 222 fixedto a rotating shaft 174.

A The vpractical applications ofV this invenconstantly tion (in so far as warp uniting `is con-v cerned) will be better understood if it isfirst stated that it is a. necessary condition that two warps, in order to be united, must be of the same draft (i. e., the same arrangement of the threads in the harnesses), but they need not be of the same color pattern; and it is the purpose of this invention to furnish a check or guide as to the correctness of selection of the threads ofthe new warp when they arenot of the same colorpatternasthe old warp. A' f e.

In tying Va striped warp to a section of an old warp, the operator must takecare thatV in determining that threads areibeing thus selected, there is-provided means for displayingi in proximityfto the selected newf warpv thread a colored-element lcorresponding .in color: to the color fof, thread which Vshould have `been selectedsby the new-warp selectors 15st.A Iftherefore the colorof the selected `new-warpA threadfdoes not correspond to the color of the aforesaid-element, the operator immediately perceivesthe existenceaof a defect or. error, .whereupon he stops thetraveling mechanism and makes the necessary correction.V y In practice, the Y operator keeps his hand Von the lever 153 while the traveling mechanism is running,

and removes his handv from the lever as soon as he. discovers an'error, the'spring 153.b immediately throwing out theclutch 147-150 assoon as the 4operator releasesthe lever 153. In. the a present embodiment, the means for indicating tothe operator the order in which thel various lcolors-'of the pattern should be selectedfcomprises an endless band 223 which is-moved step by step and which is carried by two flanged-.rollers .224 and 225. TheV roller 224 isliixed upon a shaft 226v (Fig. l). The-roller` 225. is. mounted uponV a pivotY 227 which may be secured in adjusted position upon a slotted bracket 228. Orr the .periphery of the .roller 224 .are driving studs229` (Figari) that enter perforations 230 (Fig.`2) in 'theband 223. The roller 22is intermittently rotated by a pawl 231 (Figs. 2 and 3) Y pivoted on .a lever 232-fand engagingV a ratchet wheel 233, the latter being fixed on the shaft 226. -The lever232 is pivoted on said4 shaft andv has a roller stud'that isheld needles in Contact with a cam 234y on constantly rotating shaft210 by a spring 235. A brake band. i236 preventsA movement .Lof .theiband through momentum.` l .237: is a., plate overlying `the colorband,.said plate .having a sight opening 238.

`The outerside of the band 223 is provided in any suitable Way with V.transverse stripes correspondingin color.to.the .colors of the threads off the new Warpnv The unit. .Width of-.thestripesgon tlieband 223 Amay be, say three-sixteenths of an'. inch, the length kof eachnnovement of theib'and being the same as thefunitwidth of thestripes; thusor two adjacent threadsfofthe same colort-theiband would have a? stripe.. lof thatfcolornthreeeighths of an inch Wide.

lifts his hand from the; lever 153, thereby stopping the travel ofthe'carriage 136 and the operationof themechanisms mounted on said carriage. :The operator then introduces i, the required correction; if necessary,.he ops erates either ,p air off; `selectors independently ofi vthel remainder of the mechanism infthe manner fully disclosed in the Bingham & Parker-application. Correction having been effected, the operator places his hand on the lever 153, whereupon theop'eration of the machine is resumed. i

A color band is made up for each pattern. i

The band must be at least long enough to extend from the roller 224 to the roller 225 when said rollers are nearest each other, and may be as much longerV as the pattern requires. The band may contain one or more of the repeats constituting the pattern. The ends of the band are suitably joined after the band has been placed upon the rollers 224 and 225. If desired, the band may be made of adhesive tape, the 'colored stripes consisting of pieces 223a (Fig. 2) of colored paper or the like adhering to the coated side of the tape, and the ends of the bands being overlapped. In setting the band to accord With the Warps, the operator may turn the roller 224 by means of the knurled flange 224a (Fig. 2). When the band is to be moved backward, the paWl 231 may be held out of engagement With the ratchet Wheel 233 by .means of the handle ...-llVhile 111 have herein .disclosed the invention in,.connection with asxvarp-.imitingmachine,.it:\vill1 be lunderstood that the inventioniisapplicable to other types'of machines that. operate alpen: Warp threads.
